Suitable applications for Carbopol 940 NF: Topical
Residual solvent for Carbopol 940 NF: Benzene
Recommended non-benzene substitute products for Carbopol 940 NF: Carbopol® 980 NF and Ultrez 10 NF polymers
Carbopol® 940 NF polymer is a highly efficient thickener used for formulating clear aqueous and hydroalcoholic gels. The polymer has short flow rheology similar to mayonnaise.
Lubrizol's benzene polymerized polymers do not meet the European Pharmacopeial "Carbomers" monograph because the residual benzene levels exceed the 2 ppm limit stipulated in the monograph.
